An autopsy revealed that the Ultimate Warrior died of cardiovascular disease, Phoenix authorities said on Tuesday.

Hellwig, 54, collapsed while he was walking his wife to their car at a Scottsdale hotel on April 8. The former pro wrestler was rushed to an area hospital, where he was pronounced dead.

The Ultimate Warrior was one of pro wrestling's biggest stars in the late 1980s. He began his WWE career in 1987. He defeated Hulk Hogan at WrestleMania VI to become WWE Champion.
